AGL1 — Phaseolus vulgaris

Summary

PvAGL1 (PHAVU_006G034400) on chromosome 6 of French bean encodes a MADS-box transcription factor that binds DNA and regulates transcription by RNA polymerase II. The gene is associated with the specification of floral organ, ovule, and stamen identity, as well as seed coat development, mucilage extrusion from the seed coat, and responses to high light intensity and UV-A. It has been linked to numerous reproductive and developmental traits including fruit shattering, carpel and sepal morphology, floral organ size, seed color, seed longevity, plant male sterility, flowering time, and nitrate uptake. The encoded protein localises to the nucleus, chloroplast thylakoid membrane, and other organelles. Studies of related genes in other species connect the family to silique dehiscence, valve margin development, and reproductive organ identity.
